Detailed Description
The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The method for switching antennas according to the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
With the development of technology, a plurality of antennas can be integrated into an electronic device (e.g., a 5G mobile phone terminal) at present, and when designing an antenna, a certain Imbalance exists between different antennas under the influence of an actual antenna architecture, a routing manner, material selection, and the like, where the Imbalance is referred to as an Imbalance Threshold (Imbalance Threshold). In practical application, different models have different unbalanced thresholds due to different requirements, and the same model has different unbalanced thresholds due to the influence of an integration process. In the scenes of cell edges, death handshake and the like, the received signal of the antenna is weakened, and the quality of the received signal is ensured by adopting a mode of switching the antenna, wherein the death handshake refers to the condition that the received signal of the electronic equipment is weakened due to the shielding of a palm when the palm touches an external antenna of the electronic equipment. In the process of switching the antennas, the imbalance threshold of the antennas is an important factor influencing the received signal strength of the antennas after switching. Since the imbalance threshold value is often set to a fixed value in the current electronic device, however, according to the fixed imbalance threshold value, the electronic device cannot ensure that the switching antenna can receive the electromagnetic wave signal with higher signal strength. To solve the above technical problem, as shown in fig. 1, an embodiment of the present application provides a method for switching antennas. The method may include steps 101 to 103 described below. The method is exemplified below by taking the implementation subject as the apparatus for switching the antenna.
Step 101: the means for switching antennas obtains a first signal strength of the first antenna and a second signal strength of the second antenna.
In the embodiment of the application, during the use of the electronic device, both the antennas can receive electromagnetic wave signals, and the signal strength can be detected through the received electromagnetic wave signals.
In the embodiment of the present application, the first antenna is a current receiving antenna. Note that the electronic device uses only the electromagnetic wave signal received by the first antenna (i.e., the current receiving antenna) as the communication signal at the same time.
Optionally, in this embodiment of the application, the apparatus for switching the antenna acquires the first signal strength and the second signal strength of the electronic device when detecting that the electronic device is in an abnormal environment such as a cell edge or a dead hand.
It can be understood that, a main receiving antenna (a first antenna) and a secondary receiving antenna (a second antenna) are provided in the electronic device, and in a normal environment, the main receiving antenna is sufficient to meet the communication requirement of the electronic device, and no switching of the antennas is needed to be considered.
Step 102: and the device for switching the antenna acquires a target unbalance threshold corresponding to the current use scene according to the unbalance threshold storage table.
In the embodiment of the present application, the target imbalance threshold corresponds to a communication requirement of a current usage scenario, for example, the current usage scenario is an online video, the communication requirement corresponding to the online video is focused on throughput, the current usage scenario is a voice call, and the communication requirement corresponding to the voice call is focused on reliability.
In the embodiment of the present application, different target imbalance thresholds are adopted, which may affect throughput, block error rate, and uplink power of an electromagnetic wave signal received after switching an antenna, so that a device for switching an antenna needs to obtain a target imbalance threshold corresponding to a current usage scenario, so that the electromagnetic wave signal received by the antenna after switching meets a requirement of the current usage scenario for communication quality.
Step 103: the apparatus for switching antennas switches the first antenna to the second antenna when the first signal strength, the second signal strength, and the target imbalance threshold satisfy a preset switching condition.
In the embodiment of the present application, the preset switching condition includes: the sum of the target imbalance threshold and the base threshold is less than the target difference; wherein the target difference is: a difference between the first signal strength and the second signal strength. It should be understood that the base threshold refers to the lowest imbalance threshold between different antennas. The sum of the base threshold and the target imbalance threshold is used as a comparison basis of the preset switching condition, so as to reduce the size of the target imbalance threshold and the data value of the corresponding imbalance threshold, and reduce the calculation amount.
In this embodiment of the application, when the first antenna cannot meet a signal receiving requirement, or when the second antenna signal meets a requirement better than the signal received by the first antenna, it needs to be determined whether a preset switching condition is met, so that the electronic device obtains an optimal received signal.
In this embodiment of the present application, when a preset switching condition is satisfied, the antenna switching apparatus sends a control signal to the antenna module, and performs an actual antenna switching operation to obtain an electrical signal output by the signal transmission interface corresponding to the second antenna.
In the embodiment of the present application, after the apparatus for switching antennas switches the first antenna to the second antenna, it is further required to detect whether the electronic device is in an abnormal environment such as a cell edge or a dead grip, so that the receiving antenna is switched to the first antenna when it is detected that the electronic device is not in the abnormal environment such as the cell edge or the dead grip.
In the method for switching antennas provided in the embodiment of the present application, first signal strength of a first antenna and second signal strength of a second antenna are obtained, then a target imbalance threshold corresponding to a current usage scenario is obtained according to an imbalance threshold storage table, and finally the first antenna is switched to the second antenna when the first signal strength, the second signal strength, and the target imbalance threshold satisfy a preset switching condition. Therefore, the target unbalance threshold corresponding to the current use scene is dynamically acquired, so that the switched second antenna better meets the use requirement of the current use scene on the received signal, and whether the preset switching condition is met or not is judged according to the target unbalance threshold, so that the switching time of the switched antenna better meets the actual requirement.
Optionally, in this embodiment of the application, as shown in fig. 2, before step 102, the method for switching antennas further includes step 201.
Step 201: and the antenna switching device generates an unbalanced threshold value storage table according to a preset training model.
In the embodiment of the application, the imbalance threshold storage table is used for storing the imbalance threshold and the parameter value of the communication attribute corresponding to the imbalance threshold; the communication attribute includes at least one of: throughput, block error rate, and uplink power.
In the embodiment of the application, under the current receiving environment of the electronic device, the parameter value of the communication attribute corresponding to the unbalanced threshold value of the second antenna is measured according to the preset training model, and the unbalanced threshold value and the parameter value of the communication attribute corresponding to the unbalanced threshold value are stored in the unbalanced threshold value storage table.
Therefore, the stored data in the imbalance threshold storage table is a real numerical value obtained according to the actual environment of the electronic device, so that the target imbalance threshold obtained according to the imbalance threshold storage table is more consistent with the actual application environment, and the second antenna can receive high-quality signals for the electronic device.
Further alternatively, in this embodiment of the present application, as shown in fig. 3, step 201 may be implemented by step 301 and step 302.
Step 301: the apparatus for switching antennas takes the second antenna as the current receiving antenna and measures the parameter value of the communication attribute corresponding to the imbalance threshold value.
Step 302: and the device for switching the antenna generates an unbalanced threshold value storage table according to the unbalanced threshold value and the parameter value of the communication attribute corresponding to the unbalanced threshold value.
In the embodiment of the present application, the imbalance threshold is at least one value, and the at least one value is increased by a preset step size from a preset initial value and does not exceed the maximum value N. It should be noted that, after each value of the imbalance threshold is maintained for a preset time, the parameter value of the communication attribute is obtained, so as to improve the stability of the parameter value of the communication attribute.
In this way, the electronic device measures the parameter values of the communication attributes corresponding to different imbalance threshold values in the current receiving environment, so that the generated imbalance threshold value storage table better conforms to the actual receiving situation of the second antenna, and the adaptation degree of the target imbalance threshold value acquired from the imbalance threshold value storage table and the current receiving environment can be improved.
Further alternatively, as shown in fig. 4, on the basis of generating the imbalance threshold storage table in step 201, the above step 102 may be implemented by steps 401 to 403.
Step 401: and the antenna switching device determines the target communication attribute according to the current use scene.
Step 402: and the antenna switching device determines the optimal parameter value of the target communication attribute according to the parameter value of the target communication attribute.
Step 403: and the device for switching the antenna determines a target imbalance threshold corresponding to the optimal parameter value of the target communication attribute according to the imbalance threshold storage table.
In the embodiment of the present application, the target communication attribute is any one of the communication attributes. The optimum parameter value is any one of: a maximum value of throughput, a minimum value of block error rate, and a minimum value of uplink power.
In the embodiment of the present application, the current usage scenarios are different, and the requirements for the signal quality of the electromagnetic wave signal are also different, so the apparatus for switching antennas determines the target communication attribute according to the current usage scenarios, and the target communication attribute may be throughput, block error rate, or uplink power.
In one example, the current usage scenario is online video viewing, the communication demand corresponding to online video viewing is focused on throughput, and the target communication attribute corresponding to online video viewing is throughput.
In another example, the current usage scenario is a voice call, the communication requirement corresponding to the voice call is focused on reliability, and the target communication attribute corresponding to the voice call scenario is a block error rate.
In another example, the current usage scenario is reading a document, the communication requirement corresponding to the reading document is focused on power saving, and the target communication attribute corresponding to the reading document scenario is uplink power.
Therefore, the most appropriate target imbalance threshold value is obtained according to the current use scene, so that the switching time of the switching antenna is more in line with the actual requirement, and the service quality of the terminal electronic equipment can be improved.
It should be noted that, in the method for switching an antenna provided in the embodiment of the present application, the execution main body may be an apparatus for switching an antenna, or a control module in the apparatus for switching an antenna, for executing the method for switching an antenna.
